# The length of each side of a regular polygon is 1.3 cm. The perimeter of polygon is 10.4 cm How many sides does the polygon have?

**Given:**

Length of each side of polygon = 1.3 cm

Perimeter of polygon = 10.4 cm

**
**

**To do:** Find how many sides does the polygon have.

**
**

**Solution:**

**
**Perimeter is nothing but the sum of all sides of polygon

Lets take the number of sides = n

Number of sides n = Sum of all sides of polygon $\div$ Length of each side of polygon

= $\frac{10.4}{1.3}$

= $\frac{104}{13}$ [multiply by 10 on both numerator and denominator]

n = 8

**
**

**So, the number of sides of polygon = 8**
